<p>Disclosed is a single mode optical waveguide fiber having periodic perturbations (2) in the core to provide a birefringence which mixes the polarization modes of launched ligth. In addition, pertubations (4) are introduced into the core which serve to manage total dispersion. The total dispersion of preselected segments (6, 8) of the waveguide are caused to change sign so that the sum of products, total dispersion times length (13, 15), algebraically add to a preselected value. The two distinct core perturbation types serve to control both polarization mode dispersion and total dispersion. Methods for making the subject waveguide are also discussed.</p> |
